i know this may be opinion, but what has some had with true experience on the limits of a #4 feed line? running a nos pro shot sol..i runa nos big shot plate which comes #6 feed but have a #4 on it just curious when would be a good time to change..tune wise.

 

so no one has any idea?

 

Look thru the recent threads. about a week ago there were two on this exact subject and was totally covered. One was even a vote on what the limit was. Prob can be found on the next page.

The 4an hose technically has a limit of 400hp but in most cases of 250HP+ applications people have run into volume issues and have had to upgrade to a 6an feed.
